Another Brick in the Wall

Compilers are just too picky: on one hand, they'll accept just about anything; this encourages us to feed them just about anything. On the other hand, they complain ceaselessly. Luckily, you can just pipe away your troubles to /dev/null and everything is sunshine and lollipops again. (Or fluorescent basement lighting and Pop-Tarts, take your pick.)

All is not well for AJ, however. In his world, they discovered the -Wall and --- instead of shying away --- actually use it. What's more, they actually fix warnings, like the following "unused variable warning."

Of course, he found this during the course of his job, which is (currently) to fix these kinds of problems. In this codebase --- weighing in at around 300k LOC --- this function is just par for the course.
